Description

Technical Field

[0001] The invention relates to the technical field of elevator detection equipment, and in particular to an elevator floor door strength detection device. Background Art

[0002] The elevator landing door is an important part of the elevator, generally composed of doors, guide rails, pulleys, sliders, door frames, sills and other components. The landing door should be a door without holes, and the net height should not be less than 2m. After the landing door is closed, the gap between the door leaves and between the door leaves and the columns, lintels and sills should be as small as possible. The strength of the elevator landing door is an important characteristic of the elevator landing door. In the production process of the elevator landing door, there are strict requirements for the landing door. It is necessary to carry out sampling inspection on the landing door to determine whether the strength of the landing door meets the standard.

[0003] Most of the existing floor door strength testing equipment uses a movable impact structure to perform impact testing on the door panels of the floor door, and then determines whether the floor door meets the strength standards. However, when the floor door is in a closed state, the two door panels of the floor door abut against each other, which has a supporting effect. When the floor door is in a moving state, the floor door itself has a certain moving speed. Furthermore, when the floor door is in an open state, the door panel is in an independent state. Therefore, when the door panel of the floor door is subjected to an impact test in the closed, moving and open states, the degree of deformation will be different, and the test results will also be different.

[0004] However, the existing detection equipment is applicable to a single working state of the floor door, and it is impossible to perform strength detection operations on the floor doors in different working states. If the floor door needs to be moved, it takes a long time to perform strength detection operations on a single door panel, resulting in reduced detection efficiency. Therefore, the present application provides an elevator floor door strength detection device to meet the needs. Summary of the invention

[0005] In response to the above problems, the present application provides an elevator door strength detection device.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an elevator floor door strength detection device, comprising two conveyor belts 1 distributed in parallel and two conveyor belts 2 arranged at both ends of conveyor belt 1, a channel is formed between the two conveyor belts 1 for exposing the closed position of the elevator floor door, and strength testing mechanisms are provided on the two conveyor belts 1.

[0007] It also includes lifting plates arranged on both sides of the second conveyor belt. When the two door panels of the elevator floor door are synchronously transferred to the two conveyor belts, the two door panels rise synchronously as the lifting plates rise.

[0008] The lifting plates are provided with a height adjustment mechanism that can drive them to rise and fall. The lifting plates located on both sides of the same conveyor belt 2 are connected by a transverse adjustment mechanism. When the lifting plates move away from the conveyor belt 2, the two door panels in the closed state can be separated.

[0009] Furthermore, the strength testing mechanism includes two impact weights 1 distributed from top to bottom, the two impact weights 1 are respectively located above and below the channel formed by the two conveyor belts 1, and both impact weights 1 are provided with a first rotating arm that can rotate synchronously therewith, and the first rotating arm is provided with a motor that can drive it to rotate.

[0010] Furthermore, the strength testing mechanism also includes two impact weights 2, which are respectively located above the two conveyor belts 1, and the two impact weights 2 are connected through the same second rotating arm, and the second rotating arm is provided with a motor that can drive it to rotate.

[0011] Furthermore, the height adjustment mechanism includes a lifting cylinder connected to the lifting plate, a receiving seat is provided directly below the lifting plate, a movable seat is connected to the bottom end of the receiving seat, and the lifting cylinder is arranged in the relative space between the receiving seat and the movable seat.

[0012] Furthermore, a support arm is provided on the movable seat, and a top plate parallel to the lifting plate is provided on the top of the support arm. A positioning suction cup group facing the lifting plate is provided on the top plate. When the two door panels rise synchronously to the limit height, the positioning suction cup group is adsorbed on the surface of the door panels.

[0013] Furthermore, the first rotating arm, the second rotating arm and the motor are all arranged on the same supporting frame, the supporting frame is connected to a base, and the conveyor belt 1 and the conveyor belt 2 are both arranged on the base.

[0014] Furthermore, the lateral adjustment mechanism includes two driving wheels arranged opposite to each other, the two driving wheels are connected by the same reciprocating track, and the two movable seats located on both sides of the conveyor belt are respectively arranged on two belt body parts parallel to the reciprocating track, one of the driving wheels is provided with a driving motor, the driving wheel and the driving motor are both arranged on the same guide seat, the reciprocating track is arranged in the recessed space of the guide seat, and the guide seat is arranged on the base.

[0015] Furthermore, the transverse adjustment mechanism also includes parallel guide rails arranged on the base, and the two tracks of the parallel guide rails are provided with linkage seats that can slide linearly, and the two linkage seats are respectively connected to two movable seats located on both sides of the second conveyor belt.

[0016] In summary, the technical effects and advantages of the present invention are as follows:

[0017] 1. The present invention can control the door panel of the floor door to be in a closed, open or moving state, and then simulate different working states of the elevator floor door, and perform strength detection operations on the door panels in different working states, thereby improving the comprehensiveness of the detection work and obtaining more accurate floor door strength detection results.

[0018] 2. The strength testing mechanism in the present invention can be adjusted, and the strength testing operation can be carried out in a targeted manner, which improves the diversity of the door detection work. It is suitable for different working states of the door, and during the detection process, there is no need to manually implement the impact test, which improves the safety of the detection process.

[0019] 3. The present invention can keep the landing door suspended in the air, so as to achieve an effect closer to the actual working environment of the elevator landing door. During the detection process, the door panel suspended above the conveyor belt is clamped by the lifting plate and the positioning suction cup group. During the impact operation, the door panel can be prevented from deflecting and falling, so as to facilitate the implementation of continuous strength detection operations and reduce operation errors.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0031] refer to Figure 1-4 The elevator floor door strength detection device shown in the figure comprises two conveyor belts 1 distributed in parallel and two conveyor belts 2 2 arranged at both ends of the conveyor belt 1, a passage is formed between the two conveyor belts 1 for exposing the closed position of the elevator floor door, and strength testing mechanisms are arranged on the two conveyor belts 1. The strength testing mechanism can perform an impact test on the floor door, and the staff can determine whether the floor door passes the strength test by evaluating the deformation degree of the floor door after the impact test.

[0032] It also includes a lifting plate 3 arranged on both sides of the conveyor belt 2. When the two door panels of the elevator floor door are synchronously transferred to the two conveyor belts 1, the two door panels rise synchronously with the rise of the lifting plate 3. The floor door moves upward away from the conveyor belt 1, the supporting force of the conveyor belt 1 on the floor door is released, and the floor door is kept in a suspended state, so as to achieve an effect closer to the actual working environment of the elevator floor door.

[0033] Since the two door panels of the elevator floor door have different impact resistance when they are opened and closed, in order to improve the accuracy of the elevator floor door strength detection operation, a height adjustment mechanism that can drive the lifting plate 3 to rise and fall is provided. The lifting plates 3 located on both sides of the same conveyor belt 2 are connected by a transverse adjustment mechanism. When the lifting plates 3 move away from the conveyor belt 2, the two door panels in the closed state can be separated.

[0034] During the separation of the two door panels and when they are stationary after separation, the working state of the elevator floor door moving and opening can be simulated. Afterwards, the strength test mechanism operates again to perform strength test operations on the two door panels in the two different states of moving and opening. The staff determines whether the door panels in this working state pass the strength test by evaluating the degree of deformation of the door panels after the impact test. The comprehensiveness of the detection work is improved, and more accurate results of the floor door strength test can be obtained. In the process of controlling the movement of the two door panels, there is no need for manual transfer operations, which improves operating efficiency and saves human resources. Example

[0035] like Figure 1-8 As shown, the strength test mechanism includes two impact weights 5 distributed from top to bottom. The two impact weights 5 are respectively located above and below the channel formed by the two conveyor belts 1, and the two impact weights 5 are both provided with a first rotating arm 4 that can rotate synchronously with the first rotating arm 4, and the first rotating arm 4 is provided with a motor that can drive the rotation thereof. When the two door panels of the landing door are closed, the impact weight 5 can rotate to hit the door panel of the landing door, and perform an impact test on the landing door in the closed state. Since the impact weights 5 are provided on the upper and lower sides of the landing door, the impact test operation can be performed on both sides of the landing door according to the needs.

[0036] The strength testing mechanism also includes two impact weights 2 7, which are respectively located above the two conveyor belts 1, and are connected through the same second rotating arm 6, which is provided with a motor that can drive the second rotating arm 6 to rotate. When the two door panels of the landing door are opened, the two impact weights 2 7 can perform an impact test on the two door panels, and then perform a strength test operation on the door panels of the landing door in the open state.

[0037] Through the optional strength testing mechanism, the strength testing operation can be carried out in a targeted manner, which increases the diversity of the door testing work. In addition, there is no need for manual impact testing, which improves the safety of the testing process.

[0038] It is worth mentioning that the weights of the impact weight 1 5 and the impact weight 2 7 can be adjusted according to actual testing requirements to achieve the purpose of regulating the impact force. Example

[0039] like Figure 1-8 As shown, the height adjustment mechanism includes a lifting cylinder 32 connected to the lifting plate 3, a receiving seat 31 is provided directly below the lifting plate 3, a moving seat 33 is connected to the bottom end of the receiving seat 31, and the lifting cylinder 32 is provided in the relative space between the receiving seat 31 and the moving seat 33. The lifting cylinder 32 can control the lifting plate 3 to move upward, so as to achieve the purpose of synchronously lifting the two door panels.

[0040] In order to maintain the stability of the door panel after being lifted, a support arm 34 is provided on the moving seat 33. A top plate 35 parallel to the lifting plate 3 is provided at the top of the support arm 34. A positioning suction cup group 36 facing the lifting plate 3 is provided on the top plate 35. When the two door panels rise to the limit height synchronously, the positioning suction cup group 36 is adsorbed on the surface of the door panel. Therefore, the door panel suspended above the conveyor belt 1 is clamped by the lifting plate 3 and the positioning suction cup group 36. In the process of performing the impact operation on it, the door panel can be prevented from being offset or falling, so as to facilitate the implementation of continuous strength detection operations and reduce operation errors.

[0041] In order to maintain the stability of the strength detection mechanism, the first rotating arm 4, the second rotating arm 6 and the motor are all arranged on the same supporting frame 8, the supporting frame 8 is connected to the base 9, and the conveyor belt 1 and the conveyor belt 2 are both arranged on the base 9.

[0042] The transverse adjustment mechanism includes two driving wheels 11 arranged opposite to each other, the two driving wheels 11 are connected by the same reciprocating track 12, and the two moving seats 33 located on both sides of the conveyor belt 2 are respectively arranged on two belt parts of the reciprocating track 12 that are distributed in parallel, and a driving motor 13 is arranged on one of the driving wheels 11. When the driving motor 13 is running, the reciprocating track 12 can be moved under the rotation and tensioning force of the two driving wheels 11, so that the moving directions of the two parallel belts on the reciprocating track 12 are opposite, thereby achieving the purpose of controlling the two moving seats 33 to move in opposite directions, and the lifting plate 3 and the positioning suction cup group 36 arranged on the moving seat 33 can smoothly clamp the door panel for movement.

[0043] In order to maintain the stability of the lateral adjustment mechanism, the driving wheel 11 and the driving motor 13 are both arranged on the same guide seat 10 , the reciprocating track 12 is arranged in the recessed space of the guide seat 10 , and the guide seat 10 is arranged on the base 9 .

[0044] In order to maintain the linearity of the moving seat 33 during the movement, the lateral adjustment mechanism further includes a parallel guide rail 14 provided on the base 9, and a linkage seat 15 that can slide linearly is provided on the two tracks of the parallel guide rail 14, and the two linkage seats 15 are respectively connected to the two moving seats 33 located on both sides of the conveyor belt 2 2. When the moving seat 33 moves, the linkage seat 15 slides on the parallel guide rail 14, thereby ensuring the stability of the moving seat 33 during the movement.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
