[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0034] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] The utility model provides an auxiliary transport device for escalator loaded test, such as Figure 1-Figure 6 As shown, the escalator loaded test auxiliary transport device comprises:

[0036] A loading trolley 100, wherein the loading trolley 100 comprises a vehicle body 110 and a chain plate conveyor belt 130 disposed on the vehicle body 110;

[0037] The transport mechanism 200 includes a base 210, a loading plate 220, a first linear motor 230 and a sliding clamp mechanism 240 disposed on the loading plate 220; the sliding clamp mechanism 240 moves back and forth between the escalator 300 and the loading trolley 100 under the drive of the first linear motor 230.

[0038] The chain plate conveyor belt 130 is mainly used to store weights 400. The sliding claw mechanism 240 lifts the weights 400 on the chain plate conveyor belt 130 and then uses the first linear motor 230 to pull and move them to the top of the escalator 300 for placement. During the preparation of the escalator loaded experiment, the weights 400 on the loading trolley 100 are transferred to different steps of the escalator 300 in batches.

[0039] In the present application, since the moving distance of the sliding clamp mechanism 240 is constant, the chain plate conveyor 130 is used to allow the weight 400 to continuously move toward the side of the transport mechanism 200, ensuring that the sliding clamp mechanism 240 can extract the weight 400 when it reaches the side of the loading trolley 100, and the escalator 300 rotates synchronously, moving one step each time, and when the escalator 300 moves a certain distance, it will ensure that one step is extended, and the sliding clamp mechanism 240 continuously places the weight 400 on different steps;

[0040] The sliding clamp mechanism 240 mainly consists of a base plate 241, a crossbeam 242 and a clamp assembly 243. The base plate 241 is connected to the driving slider of the first linear motor 230. The crossbeam 242 is arranged on the base plate 241. The number of the clamp assemblies 243 is not less than two groups, which are arranged on the end surface of the crossbeam 242 away from the base plate 241. The number of the clamp assemblies 243 matches the number of weights 400 placed on each step. The clamp assembly 243 is composed of an electric clamp and an electric push rod in the prior art. The weight 400 adopts the weight structure in the existing test. The weight 400 is provided with a lifting rod. The electric clamp replaces the manual grasping action. One end of the electric push rod is connected to the crossbeam, and the other end is connected to the electric clamp to realize the up and down lifting action of the electric clamp, and cooperate with the first linear motor 230 to complete the linear transmission function.

[0041] In the present application, the loading trolley 100 can load a certain number of weights 400 before the experiment begins and arrange them in order according to the array distribution. The specifications will be selected in advance according to the test needs. The loading trolley 100 will be used as a transportation device for the weights 400 for transfer or relocation. The placement work can be placed before the test starts, and after arriving at the site, it only needs to be rearranged to avoid grabbing failure;

[0042] The transport mechanism 200 is arranged on the floor plane and the distance from the escalator 300 is adjusted. After the loading trolley 100 is fully loaded with weights 400, it stops at the side of the transport mechanism 200 away from the escalator 300. In the process of transporting and placing the weights 400, the weights 400 on the chain plate conveyor 130 of the loading trolley 100 will continue to move forward after being taken away by the transport mechanism 200 for a row, so as to ensure that there are always weights 400 under the transport mechanism 200. The escalator 300 moves different steps to the side of the transport mechanism 200 away from the loading trolley 100, and the transport mechanism 200 will continuously place weights 400 on the vacant steps. The whole placing process needs to be carried out in an orderly manner with the cooperation of the escalator 300.

[0043] By cooperating with the loading trolley 100, the transport mechanism 200 and the escalator 300, the weight 400 can be placed before the escalator load test, and the staff does not need to carry the weight 400 back and forth, which reduces the workload of the staff. The mechanized equipment is used to effectively improve the efficiency of the preparatory work before the experiment, shorten the preparation time to the greatest extent, and improve the efficiency of the experiment.

[0044] As a preferred implementation in this embodiment, a storage area 120 is provided on the vehicle body 110, and the chain plate conveyor belt 130 is arranged in the storage area 120. A movable plate 140 is provided on one side of the vehicle body 110. During the transportation of the weight 400, the side of the vehicle body 110 provided with the movable plate 140 is close to the transportation mechanism 200; and the movable plate 140 is in an open state;

[0045] In this embodiment, the storage area 120 is designed as a groove structure, which meets the needs of the chain plate conveyor 130. At the same time, the storage area 120 provides a limiting area for the weight 400 to prevent the weight 400 from slipping during transportation. The movable plate 140 is connected to the vehicle body 110 with a latch structure during transportation to play a blocking and limiting role. When transporting, the movable plate 140 is opened and laid flat to make it easier for the weight 400 to move out of the storage area 120.

[0046] As a preferred implementation in this embodiment, the first linear motor 230 is arranged on a side of the loading plate 220 facing the base 210, and a second linear motor 250 is further arranged on a side of the loading plate 220 away from the first linear motor 230; a counterweight block is arranged on the slider of the second linear motor 250;

[0047] In the embodiment, the first linear motor 230 and the second linear motor 250 are both existing mature technical equipment, which are mainly responsible for the reciprocating linear motion of the counterweight block and the sliding clamp mechanism 240. In the present application, the movement direction of the counterweight block and the sliding clamp mechanism 240 is reversed with the help of the first linear motor 230 and the second linear motor 250 to avoid the tipping of one end of the transport mechanism 200 due to excessive counterweight; for example, if the sliding clamp mechanism 240 moves to the left, the counterweight block will move to the right. When the sliding clamp mechanism 240 is located above the escalator 300, the counterweight block is located above the loading trolley 100;

[0048] As a preferred implementation in this embodiment, a pull rod 211 is provided on one side of the base 210, and an auxiliary wheel 212 is provided on the side away from the pull rod 211; when the base 210 is in contact with a plane, the auxiliary wheel 212 cannot contact the ground, and when one side of the pull rod 211 is lifted, the auxiliary wheel 212 contacts the ground, and can be moved and transferred by pulling the pull rod 211;

[0049] In this embodiment, a displacement sensor and an acceleration sensor are provided inside the base 210. After the weight 400 is placed, the transport mechanism 200 is also transferred to a step of the escalator 400, and the displacement sensor and the acceleration sensor provided inside the base 210 are used to obtain the test data of the escalator 400 during the test process; the transport mechanism 200 and the weight 400 can also be connected in series using chains, ropes and other components. The structure of the weight 400 is relatively more prone to tipping. The transport mechanism 200 and the weight 400 form an integral structure. In extreme cases, the transport mechanism 200 can prevent the weight 400 from rolling and damaging the escalator;
