Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator inspection technology, specifically to a weight handling robot for elevator inspection. Background Technology
[0002] As an indispensable vertical transportation tool in modern buildings, the safety of elevator operation is directly related to the safety of public life and property. According to national standards such as the "Safety Code for Elevator Manufacturing and Installation" (GB7588-2003), elevators need to undergo type testing, periodic inspection and supervision spot checks regularly. Among them, load simulation testing is one of the core projects. This type of test verifies the elevator's balance coefficient, braking performance and running stability by simulating the car's operating state under different loads (such as no load, rated load and overload). Weights, as a standard load tool, are the core carrier for achieving accurate simulation.
[0003] In elevator testing, the main function of weights is to provide a quantifiable simulated load for the car. For example, the balance coefficient test requires adjusting the weight difference between the car and the counterweight (usually requiring a balance coefficient between 0.4 and 0.5), which necessitates using combinations of weights of different weights (such as 100kg, 200kg, 500kg, etc.) to simulate the actual load. The rated speed test requires loading weights to bring the car to 80%-100% of its rated load to verify the elevator's operational reliability under full load.
[0004] However, in the existing technology, the handling of weights mainly relies on the cooperation of a handling trolley and manual labor. The existing handling trolley does not have a lifting function, and the operator needs to bend over frequently to pick up and put down the weights, which can easily cause lumbar strain in the long run. In addition, the weights are often directly stacked on the trolley platform. If they collide with the shaft structure or door frame during the handling process, there is a risk of them falling off. The trolley is also prone to retraction due to collisions. Utility Model Content
[0005] The purpose of this invention is to provide a weight-carrying robot for elevator testing, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An elevator inspection weight handling robot includes a remote-controlled electric flatbed cart, a scissor lift platform, and a weight placement frame. The remote-controlled electric flatbed cart is equipped with a scissor lift platform, and the weight placement frame is mounted on the scissor lift platform. Slots are equally spaced on both sides of the weight placement frame. A partition plate is installed inside the weight placement frame, and the two ends of the partition plate are inserted and fixed into the corresponding slots. Positioning rods are installed at the four corners of the top of the scissor lift platform. Positioning rod sleeves are provided at the four corners of the weight placement frame, and the positioning rod sleeves are fitted onto the positioning rods. Corner anti-collision structures are installed at the four corners of the remote-controlled electric flatbed cart, and side anti-collision structures are installed on both sides of the remote-controlled electric flatbed cart.
[0008] As a further embodiment of this utility model: the corner anti-collision structure includes an upper clamping plate, a lower clamping plate, and an arc-shaped rubber block. The upper clamping plate and the lower clamping plate are respectively installed on the upper and lower sides of the remote-controlled electric flatbed. A threaded fixing assembly is provided between the upper clamping plate and the lower clamping plate. The upper clamping plate and the lower clamping plate are fixed to the remote-controlled electric flatbed by the threaded fixing assembly. An arc-shaped rubber block is installed between the upper clamping plate and the lower clamping plate.
[0009] As a further improvement of this utility model: the side anti-collision structure includes a wheel frame and a buffer guide wheel, and a number of buffer guide wheels are installed side by side on the wheel frame.
[0010] As a further improvement of this utility model, the buffer guide wheel is a rubber wheel.
[0011] As a further improvement of this utility model, the arc-shaped rubber block is bonded and fixed to the upper and lower clamping plates with glue.
[0012] As a further improvement of this utility model, handles are installed on both sides of the weight placement frame.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model sets up a partition plate inside the weight placement frame. The position of the partition plate can be flexibly adjusted. The partition plate forms multiple independent storage cavities inside the weight placement frame, avoiding wear caused by stacking and squeezing weights of different specifications, and preventing weights from falling out of the weight placement frame due to large-scale shaking and displacement during transportation.
[0015] 2. This utility model, through the combined use of a positioning rod and a positioning rod sleeve, can stably set the weight placement frame on a scissor lift platform, and can stack multiple layers of weight placement frames within the load-bearing capacity of a remote-controlled electric flatbed cart, significantly improving handling efficiency.
[0016] 3. This utility model uses a combination design of remote-controlled electric flatbed cart and scissor lift platform to realize both horizontal movement and vertical lifting of weights. Vertical lifting of weights can reduce the number of times testing personnel have to bend over to pick up and put down weights, and reduce the labor intensity of personnel during weight handling.
[0017] 4. By setting up corner anti-collision structures and side anti-collision structures, this utility model can reduce the damage to the remote-controlled electric flatcar when it accidentally collides with the shaft wall or elevator door frame, and reduce the impact force on the weights, thus protecting the safety of the weights.

[0023] 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.
[0024] Please see Figure 1-2In this embodiment of the utility model, a weight handling robot for elevator testing includes a remote-controlled electric flatbed trolley 1, a scissor lift platform 2, and a weight placement frame 5. The remote-controlled electric flatbed trolley 1 is equipped with the scissor lift platform 2, and the scissor lift platform 2 is equipped with the weight placement frame 5. The scissor lift platform 2 can reduce the number of times the testing personnel have to bend over to pick up and put down the weights by vertically lifting the weights, thereby reducing the labor intensity of personnel during the weight handling process.
[0025] Please see Figure 2 The weight placement frame 5 has slots 9 evenly spaced on both sides. A partition plate 10 is provided inside the weight placement frame 5. The two ends of the partition plate 10 are inserted and fixed in the corresponding slots 9. The position of the partition plate 10 can be flexibly adjusted. The partition plate 10 forms multiple independent storage cavities inside the weight placement frame 5, avoiding wear caused by stacking and squeezing weights of different specifications, and preventing weights from falling out of the weight placement frame 5 due to large-scale shaking and displacement during transportation.
[0026] Please see Figure 1-2 Positioning rods 4 are installed at the four corners of the top of the scissor lift platform 2. Positioning rod sleeves 8 are set at the four corners of the weight placement frame 5. The positioning rod sleeves 8 are fitted onto the positioning rods 4. Handles 11 are installed on both sides of the weight placement frame 5. The handles 11 make it convenient for personnel to move the weight placement frame 5. Through the cooperation of the positioning rods 4 and the positioning rod sleeves 8, the weight placement frame 5 can be stably set on the scissor lift platform 2. Multiple layers of weight placement frames 5 can be stacked within the load capacity of the remote-controlled electric flatbed trolley 1, which significantly improves the handling efficiency.
[0027] Please see Figure 1 , Figure 2 and Figure 4The remote-controlled electric flatbed cart 1 has corner anti-collision structures 6 installed at its four corners and side anti-collision structures 7 installed on both sides. The corner anti-collision structures 6 include an upper clamping plate 601, a lower clamping plate 602, and an arc-shaped rubber block 603. The upper clamping plate 601 and the lower clamping plate 602 are respectively installed on the upper and lower sides of the remote-controlled electric flatbed cart 1. A threaded fixing assembly 12 is provided between the upper clamping plate 601 and the lower clamping plate 602. The upper clamping plate 601 and the lower clamping plate 602 are fixed to the remote-controlled electric flatbed cart 1 by the threaded fixing assembly 12. The threaded fixing assembly 12 includes a screw and a nut. The remote-controlled electric flatbed cart 1 has a hole for the screw to pass through. An arc-shaped rubber block 603 is installed between the upper clamping plate 601 and the lower clamping plate 602. The side anti-collision structure 7 includes a wheel frame 701 and a buffer guide wheel 702. Several buffer guide wheels 702 are installed side by side on the wheel frame 701. When the weight handling robot rotates, its side is prone to collide with the door frame. At this time, the side anti-collision structure 7 will contact the door frame first. The buffer guide wheel 702 will buffer the impact at the moment of collision. At the same time, the buffer guide wheel 702 will convert the impact force generated by the collision into the rotational power, which will cause the buffer guide wheel 702 to rotate. The rotation will restore the forward direction of the weight handling robot.
[0028] The buffer guide wheel 702 is a rubber wheel, and the use of rubber material can make the buffering effect of the guide wheel better.
[0029] The arc-shaped rubber block 603 is bonded and fixed to the upper clamping plate 601 and the lower clamping plate 602 with glue. The glue bonding can increase the connection strength between the arc-shaped rubber block 603 and the upper clamping plate 601 and the lower clamping plate 602, and reduce the risk of the arc-shaped rubber block 603 falling off.
[0030] The working principle of this utility model is as follows:
[0031] After testing, the inspectors lift the weights one by one and place them into the weight placement frame 5. Then, they separate adjacent weights using the partition plate 10. After filling the first layer of weight placement frame 5, they stack the second layer of weight placement frame 5 on top of the first layer, ensuring that the positioning rod sleeves 8 at the four corners of the weight placement frame 5 pass through the positioning rods 4 to ensure the stability of the weight placement frame 5. After the weights are placed, the remote-controlled electric flatbed cart 1 is started to transport the weights to the storage location. During the transportation process, the scissor lift platform 2 works in conjunction with the remote-controlled electric flatbed cart. The vertical position of the weight placement frame 5 can be adjusted according to the height of the testing point and the height of the operator. When the electric flatbed cart arrives at the target floor, the scissor lift platform 2 drives the scissor arm to extend via the electric push rod, raising the weight placement frame to the natural picking and placing height for the operator to stand at, so that the operator can pick up and place the weights directly without bending over.
[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
