Technical Field

[0002] Elevator guide rails are elevator components made of steel rails and connecting plates. They are divided into car guide rails and counterweight guide rails. They are divided into three types according to the cross-sectional shape: T-shaped, L-shaped and hollow. While playing a guiding role, the guide rails bear the impact force of the car and elevator during braking, the impact force of the safety clamp during emergency braking, etc. The magnitude of these forces is related to the load and speed of the elevator, so the guide rails should be selected according to the elevator speed and load. Usually, the car guide rail is called the main rail, and the counterweight guide rail is called the auxiliary rail;
[0003] Traditional elevator guide rail detection devices have some shortcomings. In the elevator guide rail production project, in order to ensure the production quality of the elevator guide rail, it is often necessary to test its bending resistance. The traditional detection device directly applies pressure to the elevator guide rail to detect the bending resistance of the elevator guide rail. During the detection process, the detection device directly contacts the elevator guide rail, which makes it impossible to adjust the contact point between the elevator guide rail and the detection device, thereby making it impossible to detect the accurate point of the elevator guide rail and the inability to apply stable bending force to the elevator guide rail.

DETAILED DESCRIPTION
[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0020] like Figure 1-4 As shown, an elevator guide rail detection device comprises an operating platform 1, wherein a bending detection mechanism 5 is arranged at the upper end of the operating platform 1, wherein the bending detection mechanism 5 comprises a bottom plate 51 fixedly connected to the upper end of the operating platform 1, wherein one end of the bottom plate 51 is fixedly connected to a guide plate 52, wherein the upper end of the bottom plate 51 is fixedly connected to a hydraulic cylinder 53, wherein a connecting ring 54 is installed at the telescopic end of the hydraulic cylinder 53, wherein one end of the connecting ring 54 is fixedly connected to a spring 510, wherein the other end of the spring 510 is fixedly connected to a fixing ring 59, wherein both sides of the connecting ring 54 are fixedly connected to fixing frames 55, wherein the inner side of the fixing frame 55 is movably connected to a movable rod 56 via a rotating shaft, wherein the inner side of the movable rod 56 is movably connected to a docking rod 57 via a rotating shaft, wherein the outer side of the docking rod 57 is movably connected to a connecting piece 58 via a rotating shaft away from the movable rod 56, wherein both sides of the fixing ring 59 are connected to the connecting piece 58, wherein a push rod 511 is fixedly connected to the inner side of the fixing ring 59, wherein a pressure head 512 is fixedly connected to the other end of the push rod 511.
[0021] In this embodiment, a sliding groove 513 is opened at the upper end of the guide plate 52, and a moving block 514 is slidably connected to the inner side of the sliding groove 513. The lower end of the guide plate 52 is fixedly connected to the side of the upper end of the operating table 1 close to the base plate 51. The axis lines of the connecting ring 54, the fixing ring 59, and the push rod 511 are located on the same straight line. The upper end of the moving block 514 is fixedly connected to the lower end of the fixing ring 59. The movable rod 56 and the docking rod 57 form a cross shape. The number of the fixed frame 55, the movable rod 56, the docking rod 57, and the connecting piece 58 are all two groups.
[0022] Specifically, the hydraulic cylinder 53 is started to push the connecting ring 54 outward, and the connecting ring 54 pushes the fixing ring 59 through the spring 510, and the fixing ring 59 drives the moving block 514 to slide inside the sliding groove 513, so that the fixing ring 59 drives the push rod 511 to move, and the pressure head 512 contacts the elevator guide rail. At this time, observe whether the contact point between the pressure head 512 and the elevator guide rail is correct. If it is not correct, since the pressure head 512 is only pushed by the hydraulic cylinder 53 to contact the elevator guide rail through the spring 510, the pressure head 512 simply contacts the elevator guide rail, so that there is no large friction between the two, and then the elevator guide rail is pushed to slide inside the placement rack 2. The contact point between the elevator guide rail and the pressure head 512 can be adjusted, and the contact point of the elevator guide rail can be adjusted to correctly correspond to the pressure head 512. By starting the hydraulic cylinder 53 and making the hydraulic cylinder 53 push the connecting ring 54 to move, and then making the connecting ring 54 push the fixing ring 59 to move through the spring 510, and making the push rod 511 push the pressure head 512 to contact the elevator guide rail, the purpose of making the pressure head 512 correspond to the contact point of the elevator guide rail when the bending force is applied to the elevator guide rail can be achieved. Then, the contact point between the elevator guide rail and the pressure head 512 can be adjusted, and the contact point of the elevator guide rail can be adjusted to correctly correspond to the pressure head 512, so that the elevator guide rail can be subjected to a stable and accurate bending test.
[0023] In this embodiment, a placement rack 2 is fixedly connected to one side of the upper end of the operating table 1 close to the guide plate 52, an equipment bin 3 is installed on the outer side of the operating table 1, an indicator light 4 is installed on the upper end of the equipment bin 3, and there are two groups of placement racks 2.
[0024] Specifically, the T-shaped elevator guide rail is clamped in the inner side of the placement rack 2, so that the placement rack 2 limits the elevator guide rail on the operating platform 1.

At this time, observe whether the contact point between the pressure head 512 and the elevator guide rail is correct. If it is not correct, since the pressure head 512 is only pushed to contact the elevator guide rail by the hydraulic cylinder 53 through the spring 510, the pressure head 512 simply contacts the elevator guide rail, so that there is no large friction between the two, and then the elevator guide rail is pushed to slide inside the placement frame 2, and the contact point between the elevator guide rail and the pressure head 512 can be adjusted, and the contact point of the elevator guide rail is adjusted to the correct The hydraulic cylinder 53 is started again to push the connecting ring 54, so that the connecting ring 54 compresses the spring 510, and the spring 510 transmits the elasticity to the push rod 511, and at the same time, the angle between the movable rod 56 and the docking rod 57 is gradually reduced, so that the force of the push rod 511 pushing the pressing head 512 is gradually increased, and the elevator guide rail can be stably and accurately bent. By starting the hydraulic cylinder 53 and pushing the connecting ring 54 to move, the connecting ring 54 pushes the fixed ring 59 to move through the spring 510, and the push rod 511 pushes the pressing head 512 to contact the elevator guide rail, the purpose of making the pressing head 512 correspond to the contact point of the elevator guide rail when the bending force is applied to the elevator guide rail can be achieved, and then the contact point between the elevator guide rail and the pressing head 512 can be adjusted, and the contact point of the elevator guide rail is adjusted to correctly correspond to the pressing head 512, so that the elevator guide rail can be stably and accurately bent.
