Description

Technical Field

[0001] The utility model relates to the technical field of elevator accessory detection, in particular to an elevator guide rail strength detection structure. Background Art

[0002] Elevator guide rails are elevator components composed of steel rails and connecting plates, usually used for guiding and supporting elevator cars. In order to ensure the application stability of elevator guide rails, the strength of the guide rails must usually be tested. The main force directions of the guide rails during use are vertical and horizontal, so the vertical and horizontal directions of the guide rails need to be tested.

[0003] In the inspection process of modern elevator guide rails, the strength test is mainly completed by detecting the vertical and horizontal force directions of the elevator guide rails pushed by the cylinder, and then using a micrometer and a detector to detect the degree of deformation. However, during the inspection process, the elevator guide rails are placed on a supporting device, and the ends of the elevator guide rails need to be fixed. At present, bolts are mainly used for pushing and fixing, which is cumbersome to operate and is prone to damage to the thread of the bolts during the strength inspection of the elevator guide rails. In view of this, in-depth research was conducted on the above-mentioned problems, and this case was created. Utility Model Content

[0019] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0020] See also Figures 1 to 3 As shown, according to the present application, an elevator guide rail strength detection structure, the support part of the detection structure includes a support base 1, a support column 2 and a support top plate 3, wherein the support base 1 is the bottommost supporting plate, and the support column 2 is integrally extended from one side of the support base 1, and the support top plate 3 is lifted by the support column 2, and the lowering space for guide rail strength detection is located between the support top plate 3 and the support base 1, and at the same time, a control column 5 is provided on one side of the support base 1, and a micrometer detector 6 is mounted on the control column 5, and the position of the micrometer detector 6 on the control column 5 is adjusted by adjusting the micrometer detector 6, so as to detect any height point of the elevator guide rail to be detected;

[0021] Specifically, a detection propulsion cylinder 4 is provided on the support top plate 3, and a detection propulsion seat 7 is fixedly connected to the telescopic end of the detection propulsion cylinder 4. A detection support seat 8 is fixedly provided on the support base 1 corresponding to the detection propulsion seat 7. The guide rail material used for detection is arranged between the detection propulsion seat 7 and the detection support seat 8, which plays the role of limiting and fixing the end. During detection, the detection propulsion cylinder 4 pushes the detection propulsion seat 7 to apply force to the guide rail profile to be detected, and cooperates with the micrometer detector 6 to detect the strength data of the guide rail profile;

[0022] Furthermore, in order to avoid damage to the fixing components fixing the ends of the detection profiles during the detection process of the elevator profiles, the present application adopts a detection push seat 7 and a detection support seat 8 symmetrically provided with detection fixing components 9 of the same shape. Specifically, the detection fixing component 9 at least includes a positioning slot 91 and two pairs of positioning guide rails 92. The detection push seat 7 and the detection support seat 8 are symmetrically provided with positioning slots 91, and the two pairs of positioning guide rails 92 are respectively arranged around the positioning slots 91. The positioning guide rails 92 are provided with reinforced push seats 93 in pairs, and the tail end of the reinforced push seat 93 is connected to a scissor pusher 94;

[0023] In the specific implementation process, after the end of the profile to be inspected is inserted into the positioning slot 91 through the positioning slot 91, the initial position of the profile to be inspected is fixed, and the reinforced push-up seat 93 on it is limited and guided by the positioning guide rails 92 around the ring cloth, and further the scissor-fork structure design of the scissor-fork pusher 94 is used to push the reinforced push-up seat 93 to fit the profile to be inspected for limiting the position. At the same time, the scissor-fork pusher 94 can effectively share the force of the screw in the force direction.

[0024] Furthermore, a pair of vertical guide columns 10 are arranged on both sides of the detection support seat 8 on the support base 1 and are connected to the support top plate 3. The pair of vertical guide columns 10 are used to assist in fixing the support top plate 3. At the same time, a pair of balance plates 11 are extended from both sides of the detection propulsion seat 7. A pair of balance grooves are provided on the pair of balance plates 11. The pair of balance grooves are sleeved on the pair of vertical guide columns 10. The pair of balance grooves on the pair of balance plates 11 are matched with a pair of vertical guide rods to play a guiding and limiting role.

[0025] Furthermore, the positioning slot 91 is a groove of a rectangular structure, and the two pairs of positioning guide rails 92 are two pairs of long strips with convex grooves in the center. The positioning guide rails 92 play both a limiting role and a guiding role for strengthening the push-up seat 93.

[0026] Further, the scissor-fork thruster 94 includes a fixed seat 941, which is assembled at the end of the positioning guide rail 92. A pair of transverse slide grooves 942 are extended from both sides of the fixed seat 941. A pair of transverse slide blocks 943 are assembled in the pair of transverse slide grooves 942. Two pairs of scissor-fork rods 944 are movably connected to the pair of transverse slide blocks 943 respectively. One pair of scissor-fork rods 944 in the two pairs are movably connected to the reinforced push-up seat 93, and the other pair of scissor-fork rods 944 in the two pairs are movably connected to the threaded adjustment sleeve 945. An adjusting bolt 946 is movably connected to the fixed seat 941, and the adjusting bolt 946 is threadedly engaged with the threaded adjustment sleeve 945.

[0027] In the specific implementation process, the adjusting bolt 946 is movably installed through the fixing seat 941, and it also serves as a basic fixing structure to withstand the detection reaction force. The fixing seat 941 is fixed to the end position of the positioning guide rail 92 by at least two pairs of bolts, and a pair of horizontal slide grooves 942 are extended from its two wings. The pair of horizontal slide grooves 942 is assembled with a pair of horizontal sliders 943. The adjusting bolt 946 at the rear is rotated to engage with the threaded adjustment sleeve 945, so that the adjusting threaded sleeve drives the two pairs of scissor rods 944 to perform scissor movement, and the adjustment is increased. The relative positions of the strengthened push-up seat 93 and the fixed seat 941, a pair of transverse sliders 943 and a pair of transverse slide grooves 942 serve the purpose of controlling the directional variables of the control column 5 during the scissor-fork movement. At the same time, when subjected to a reaction force, since only the front pair of scissor-fork rods 944 are connected to the strengthened push-up seat 93, the reaction force exerted on the strengthened push-up seat 93 directly acts on the pair of scissor-fork rods 944 and the pair of transverse sliders 943 and transverse slide grooves 942, and not much is transmitted to the rear adjusting bolt 946, so the pressure on the thread of the adjusting bolt 946 is relatively small.

[0028] From the above, it can be generally known that in the elevator guide rail strength detection structure, the two ends of the profile to be detected are limited by the upper and lower symmetrical detection and fixing components 9 during the strength detection process of the elevator guide rail. The detection and fixing components 9 use a scissor-type thruster 94 to cooperate with the reinforced push-up seat 93 to contact the detection profile. When the reverse force of the deformation caused by the pushing and pressing of the detection profile acts on the reinforced push-up seat 93 and the scissor-type thruster 94, it is effectively shared, thereby reducing the reverse force borne by the bolt positioning and effectively protecting the screw thread.
